I have a beefsteak tomato planted in an Earthbox. This plant is showing symptoms of Late Blight and it still has two dozen tomatoes that are starting ripen on it. Is there any way to get these tomatoes to fully ripen off of the vine? Is the soil still be able to be used for other plants? Is the soil still safe to use? If it's not, then is there anything that can be done to decontaminate the soil, if possible? Solarization?
